Goodyear is trying soybean oil as a petroleum replacement for tires. Could it be a magic bullet?
The company says the advantages include blending better with silica, also used in tire-making, increases tread life, reduces Goodyear’s energy consumption and oil consumption by 7 million gallons a year!
You can’t buy bean-oil tires yet, though. Still at the prototype stage. If testing at Goodyear’s track in Texas goes well, you could be able to buy soybean tires by 2015, the tiremaker says.
No hint of whether they’d be more expensive than rubber tires.
